ROLLING WINDOW S GREEN Filed Nov. 4, 1927 glwuenkw GEQESAGERS Patented Dec. 10, 1929 GEORGE F. SAGER'S, OF DES MOINES, IOWA ROLLING WINDOW SCREEN Application filed November The object of this invention is to provide an improvement in rolling window screens of the type in which the roller is carried by the window frame and the free edge of the screen is detachahly connected to a window sash and movable therewith.

More specifically the object of the invention is to provide an improved construction and means for mounting the roller which carries the screen in a suitable position relative to the window frame.

With these and other objects in view, my invention consists in the construct-ion, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which Figure 1 is an inside elevation showing my improved screen in position for use and attached to a window sash which is partially opened.

Figure 2 is a vertical section on an enlarged scale on the line 22 of Figure 1.

Figure 8 is a longitudinal section through a roller assembly embodying my invention, a portion being broken away.

Figure 4: is a crosssection through the roller on the line H of Figure 3.

Figure 5 is a detail cross-section through the roller, showing the means for attaching the lower edge of the screen thereto.

In the construction of the device as shown, the numerals 10 and 11 designate end plates which are adapted to be attached to the inner faces of the side frame members 12 and 13 respectively of a window frame. The end plates 10 and 11 are located just outside of the window stops 14 and 15 which help to form the guides for a sliding sash such as 16. The end plates are shown as mounted at the lower part of the Window frame and resting on the window sill 1. Each end plate 10 and 11 has a peripheral flange 18 projecting toward the median line of the window frame upon which a housing plate 19 rests.

Centrally of their inner faces, the end plates 10 and 11 are formed with tubular journals 23 and 24: respectively. A roller 25 of cylindrical form is provided and said 4, 1927. Serial 1T0. 231,039.

sheet metal roller is of less length than the widtl'i of the window frame or the distance between the end plates 10 and 11. At one end the roller 25 contacts with the end plate 1.0 and has that end turned inwardly to form an elongated tubular bearing 26 adapted to engage and rotate freely on the joural of said end plate. At the opposite end the roller is open and a sleet metal cartridge 27 of tubular form is slidably mounted in said open end. At its inner end the cartridge 27 is open and its outer end is turned in to form an elongated tubular bearing 28 adapted to engage and rotate freely on the journal 24: of the end plate 11. A coil spring 29 is mounted lengthwise within the roller 25 and said spring has mounted in and attached to one of its ends a plug 80 provided with. a projection 31 which is square or otherwise angular in. cross-section and extends within the tubular journal 23 of the end plate 10 which is similarly formed in cross-section internally. This arrangement holds one end of the spring 29 rigidly against rotation so that power may be stored in the spring. At its opposite end the spring 29 is provided with a plug 32 rigidly secured therto, which plug extends within and is attached to the inner end portion of the cartridge 27. To provide means whereby the roller 25, cartridge 2 and "spring 29 are secured together for con junctive rotary movement, I have provided a flange 38 which projects inwardly from the shell of the roller and extends through a longitudinal slot 3% formed in the can tridge and into a longitudinal groove 85 formed in the plug 32 of the spring, as shown mrticularly in Figures 3 and 4. The slot 34 of the cartridge is of greater length. than the flange 33 so as to permit longitudinal adjustment of the cartridge in the roller.

A flexible window screen 86 is adapted to be attached at its lower margin to the roller 25 and at its upper margin to the lower edge of the sash 16, and said screen is of suflicient width to extend substantially from the end plate 10 to the end plate 11 and to bridge the space between the side members of the window frame. At its lower margin the screen 36 is provided with a channel-shaped binding 37 rigidly secured thereto and said binding is formed at intervals with hooks 38 adapted to engage in spaced slots 39 formed in the shell of the roller 25 as shown particularly in Figure 5, whereby the screen is detachably secured to the roller and adapted to be wound thereon.

I I claim as my invention:

7 1. In a device of the class described, a hollow roller formed with a bearing at one end, a cartridge of tubular form fitted to and slidable in the opposite end of said roller,

5 said'cartridge being formed with a bearing at its'outer end, a coil spring mounted within said roller and fixedly secured at one end, and a plug partially received within and secured to said spring and partially received within the inner end of said cartridge, together with means on said roller engaging said plug and cartridge to prevent relative rotation of said plug, cartridge and roller.

2. In adevice of the class described, a hollow roller formed with a bearing at one end,

a cartridge of tubular form fitted to and slidable in the opposite end of said roller, said cartridge being formed with a bearing at its outer end, and a coil spring mounted with in said roller, fixedly secured at one end, and

having secured to its opposite end a plug 7 which is received within the inner end of said cartridge, said cartridge and plug being formed with registering longitudinal slots,

said roller being formed with an inturned flange 'projectingwithin the slots of said cartridge and plug.

3. In a rolling window screen, a hollow sheet metal roller having an end member '40 turned inwardly to form an elongated tubularbearing, a journal to receive said bearing, said journal being formed with an angular recess, a sheet'metal cartridge mounted for longitudinal adjustment in the other end of said roller, means for securingsaidcartridge to said roller for conjunctive rotary movement, a coil spring mounted in said roller r andfixed at its inner end to said cartridge, a

plug in'the opposite end of said spring having an angular projection received in the re .cess of said journal, said cartridge having an outer end member turned inwardly to form an elongated tubular bearing, and a journal to receive the bearing of said cartridge.
